Examples of Atoms in Everyday Life for Kids

📚 Quick Study Guide

• ⚛️ Atoms are the basic building blocks of everything around us.
• 💧 Atoms combine to form molecules. For example, two hydrogen atoms ($H$) and one oxygen atom ($O$) make a water molecule ($H_2O$).
• 💨 Different elements have different types of atoms. Examples include Hydrogen (H), Oxygen (O), Carbon (C), and Iron (Fe).
• 🍎 Everything you can touch, see, or smell is made of atoms, from your toys to your food!
• 💡 Atoms are incredibly small, way too small to see with your eyes alone.
